connect input harness
The Goat ESC has the industry-standard receiver input connector on a user-
replaceable input harness & works with all major radio brand's new receivers.
However, some very old receivers must have the wiring sequence in the
plastic 3-pin connector housing changed. This is important, because receiver
& servo electronics may be damaged if the sequence is incorrect.

JR • Hitec • Futaba • New KO • Airtronics Z
JR, Hitec, Futaba, new KO, & Airtronics Z receivers do not need input
harness re-wiring. Airtronics Z receivers have blue plastic cases & new KO
cases have tabs on the input harness openings as in Figure 1.
• Plug one end of the input signal harness into the THROTTLE CHANNEL (#2) of
receiver with the BLACK wire toward the outside edge of receiver case.
• Plug the other end of the input harness into 3-pin header on the
ESC case with the WHITE wire toward the outside of the ESC.

If you have an older KO or Sanwa/Airtronics, you must change the sequence
of the ESC's input harness wires--Old Sanwa/Airtronics cases are black color &
Old KO cases do not have tab openings, as in Figure 2 above.
• Using a small flat blade screwdriver, remove the red & black wires from the plastic
housing at the receiver end of the input harness as in Figure 3 below.
• Interchange the red and black wires in the plastic 3-pin connector housing at
the receiver end of the input harness.
• Insert modified end of the harness into the THROTTLE CHANNEL (#2) of receiver
with the RED wire toward the outside edge of receiver case.
• Plug the other end of the input harness into the ESC with the WHITE wire toward
the 'S' (signal) marking on the ESC's case.

ESC MOUNTiNG
Mount the speed control so that the power wires as far away from other
electronics as possible. Make sure that the speed control or the power
wires will not interfere with any moving parts in the vehicle. Select a
location that has good cooling and allows airflow through heat sinks.
If the ESC gets air flow, it will run cooler; and that means it will be more efficient!
1. MOUNT SPEED CONTROL IN VEHICLE
Use the included double-sided tape to mount the speed control in vehicle
. Avoid contact with side walls or other chassis components
(do not use glue)
to avoid vibration damage
.
Be sure receiver & antenna are mounted as far from ESC, power wires, battery,
& servo as possible--these components all emit RF noise when throttle is
applied. On graphite or aluminum chassis vehicles, it may help to place
receiver on edge with crystal & antenna as far above chassis as possible.
Note: Mount antenna as close to receiver as possible--trail any excess wire off top
of antenna mast (cutting or coiling excess antenna wire will reduce radio range).
2. SECURE POWER CAPACITOR TO CHASSIS
Use included double-sided tape, or a tie-wrap, to mount Power Capacitor
to the vehicle's chassis or shock tower. Capacitor can also be tie-wrapped
along the power wires--this requires less space on the chassis and provides
good isolation from vibration.
3. INSTALL ON/OFF SWITCH
Use a screw or the included double-sided tape, and mount the switch
where it will be easy to access--be sure to select a position where it will
not get damaged or get switched OFF during a crash or roll-over.

1. MOTOR CAPACITORS NOT NEEDED
Novak brushless motors do not require external motor capacitors.
2. DO NOT USE SCHOTTKY DIODES
Schottky diodes must NOT be used with reversible ESCs (including brushless).
Schottky diode usage will damage the ESC & void warranty.
3. FACTORY-INSTALLED POWER CAPACITOR REQUIRED
The factory-installed Power Capacitor MUST be used with brushless &
brush-type motors.
If Power Capacitor becomes dented or damaged, ESC failure can
occur--replace immediately. Longer Power Capacitor wires will decrease performance.
4. SOLDER MOTOR POWER WIRES TO MOTOR
*Skip this step if installing complete system with ESC factory-wired to motor.
a. Cut the BLUE, YELLOW, & ORANGE silicone motor power wires to the
desired length, and strip 1/8-3/16" of insulation from the end of each
wire. Tightly twist the exposed strands of wire, and tin the exposed end
section of each wire with solder with a good, high heat iron.
b. Solder the ESC's BLUE Phase 'A' motor wire to the motor's phase 'A' solder
tab. Apply heat to exposed wire with soldering iron, and add solder to
the tip of the iron & the wire--Add just enough solder to form a clean &
continuous joint from the solder tab up onto the wire.
IMPORTANT NOTE: DO NOT OVERHEAT SOLDER TABS
Prolonged/excessive heating of solder tabs (motor or ESC) will cause damage.
c. Solder the ESC's YELLOW Phase 'B' motor wire to the motor's phase 'B'
solder tab as described in Step 5B above.
d. Solder the ESC's ORANGE Phase 'C' motor wire to the motor's phase 'C'
solder tab as described in Step 5B above.
Note: Make sure no wire strands have strayed to an adjacent solder tab, this will
result in short-circuiting & severe ESC damage, which will void the warranty.
5. CONNECT MOTOR'S SENSOR HARNESS TO ESC
Insert the 6-pin connector on the end of the motor's Teflon sensor wires
into ESC's sensor harness socket--the connector is keyed and will only go
together in one direction. Spiral wrap can be used to protect sensor wires.
6. CONNECT SPEED CONTROL TO BATTERY PACK
Connect the speed control's Tamiya-style JST battery connector to a charged
4 to 7 cell (1.2VDC/cell) or 2-cell LiPo battery pack.

1. DISCONNECT BRUSHLESS MOTOR SENSOR HARNESS
The Goat Brushless/Brush Crawler speed control automatically switches to
Brush-Mode when the ESC's power is switched ON and no brushless motor
sensor harness is connected to it.
2. MOTOR CAPACITORS
Electric brush-type motors generate RF noise that causes interference. The
included 0.1µF (50V) non-polarized, ceramic capacitors must be used on
all motors to reduce motor noise & prevent ESC damage.
Note: Some motors come with built-in capacitors. If your motor only has 2 capacitors, you
need to install a capacitor between the positive & negative motor tabs––If you experience radio
interference with built-in capacitors only, install external ones.
Solder 0.1µF (50V) capacitors between:
• POSITIVE (+) & NEGATIVE (–) motor tabs.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (–) motor tab & GROUND tab*.
DO NOT USE SCHOTTKY DIODES
3. SOLDER ESC'S BLUE & YELLOW WIRES TO MOTOR
With brush-type motors, the ESC's BLUE power wire goes to the NEGATIVE (–)
Motor Tab & the YELLOW power wire goes to the POSITIVE (+) Motor Tab.
a. Cut the ESC's BLUE & YELLOW silicone motor power wire to the desired
length to reach the motor, and strip about 1/4" of insulation from the
end of each wire. Twist & tin the ends of each wire (individually).
b. Solder the BLUE motor power wire to the NEGATIVE (–) Motor Tab.
c. Solder the YELLOW motor power wire to the Positive (+) Motor Tab.
4. CONNECT SPEED CONTROL TO BATTERY PACK

8. RETURN TRANSMITTER THROTTLE TO NEUTRAL
(as shown here), solder the

• Use polarized connectors. Reverse voltage will damage ESC & void warranty.
• Use a female connector on battery packs to avoid shorting.
When wiring the vehicle's electronics, shorter length wires & clean/neat
installations will give you better performance, higher efficiency, & less
radio problems (glitching, poor range, etc.). Try your best to keep all
power wires away from signal wires, the receiver, and the antenna.
